Detailed Description
The present application will be described in further detail with reference to the drawings and examples, in order to make the objects, technical solutions and advantages of the present application more apparent. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the application.
With the continuous development of the nuclear power field, the number of nuclear power equipment is also increased, and in order to ensure stable signal transmission, a plurality of identical signal transmission links are generally configured in a gateway at the same time, namely, the gateway with redundant configuration is adopted for signal transmission.
However, under the condition that the gateway itself fails, each transmission link in the gateway fails at the same time, that is, the gateway sends an error operation signal to the nuclear power equipment, so that the nuclear power equipment has dangerous situations such as tripping and the like, and the operation stability of the nuclear power equipment is reduced.
Based on this, in one embodiment, a nuclear power instrumentation system (Distributed control system, DSC) employs a gateway to transmit signals to each nuclear power plant (e.g., turbine monitoring and conditioning system, reactor control rod system, reactor protection system, power plant radiation monitoring system, fire detection system, etc.); further, as shown in fig. 1, a signal transmission method of a nuclear power device is provided, and the method is applied to a processor in a gateway for illustration, and specifically includes the following steps:
s101, acquiring a current indication signal sent by a nuclear power instrument control system at the current moment.
The nuclear power instrument control system is used for controlling each nuclear power device in the nuclear power plant to operate; the current indication signal refers to a signal which is sent to the nuclear power equipment by the nuclear power instrument control system and used for indicating the operation of the nuclear power equipment.
Optionally, the nuclear power instrument control system sends the current indication signal of the current moment to the gateway according to the running data of the current moment of the nuclear power plant based on the preset signal sending frequency; correspondingly, the gateway can directly acquire the current indication signal at the current moment.
S102, determining a current output signal according to the current indication signal and the gateway state signal at the current moment.
Wherein the gateway status signal is used to represent the status of the gateway; the current output signal refers to a signal sent by the gateway to the nuclear power plant.
It will be understood that in practical application, a nuclear power device is taken as a refrigerator and a heater for illustration, and in the case of normal gateway, if an overvoltage problem occurs, the nuclear power instrument control system sends a low-level signal to the refrigerator and the heater to indicate the refrigerator and the heater to trip, however, in the case of failure of the gateway, even if the nuclear power instrument control system wants to send a high-level signal to the refrigerator and the heater to indicate the refrigerator and the heater to operate normally, the gateway directly sends a low-level signal to the refrigerator and the heater to further cause unexpected tripping of the refrigerator and the heater.
Optionally, in order to avoid the above problem, in this embodiment, the gateway may automatically generate the gateway status signal at the current time according to the running status at the current time. For example, if the running state of the gateway at the current moment is normal, a gateway state signal with a high level may be generated; if the running state of the gateway at the current moment is a fault, a low-level gateway state signal can be generated.
Further, the current indication signal and the gateway state signal at the current moment can be simultaneously input into a first signal generation model integrated into the gateway, and the first signal generation model determines the current output signal according to the current indication signal, the gateway state signal and the model parameters.
S103, transmitting a current output signal to the nuclear power equipment so that the nuclear power equipment can operate based on the current output signal.
Optionally, after determining the current output signal, directly transmitting the current output signal to the nuclear power equipment; accordingly, the nuclear power plant may operate based on the current output signal after receiving the current output signal.
In the signal transmission method of the nuclear power equipment, the current output signal is determined according to the current indication signal sent by the nuclear power instrument control system at the current moment and the gateway state signal at the current moment, and the current output signal is transmitted to the nuclear power equipment, so that the nuclear power equipment operates based on the current output signal. Compared with the related method, the method has the advantages that the gateway state signal is introduced by adopting the method only for signal transmission by adopting the gateway with redundant configuration, and the correct current output signal can be determined based on the gateway state signal under the condition that the gateway fails, so that the accuracy of the current output signal output by the gateway is ensured, and the running stability of the nuclear power equipment is further ensured.
In order to ensure the accuracy of the current output signal, in this embodiment, an alternative method for determining the current output signal is provided, as shown in fig. 2, which specifically includes the following steps
S201, processing the gateway state signal and the current indication signal to obtain an auxiliary signal.
The auxiliary signal is a signal which plays an auxiliary role in the process of determining the current output signal.
Alternatively, the gateway status signal and the current indication signal may be simultaneously input into the second signal generation model, and the second signal generation model determines the auxiliary signal according to the gateway status signal, the current indication signal and the model parameters.
Or in order to facilitate signal transmission, the gateway state signal and the current indication signal are both expressed by logic levels; correspondingly, in order to ensure the accuracy of the auxiliary signal, another way of determining the auxiliary signal may be to take a non-operation on the current indication signal to obtain an alternative signal; and performing logical AND operation on the gateway state signal and the alternative signal to obtain an auxiliary signal.
Wherein, the alternative signal refers to a signal obtained in the process of determining the auxiliary signal; in this embodiment, when the gateway status signal is at a high level, it indicates that the gateway operation status is normal operation, and when the gateway status signal is at a low level, it indicates that the gateway operation status is failure. For example, in the case where the gateway operation state is normal operation, if the current indication signal is 1, the alternative signal is 0 and the auxiliary signal is 0.
S202, determining a current output signal according to the auxiliary signal and the current indication signal.
Alternatively, the auxiliary signal and the current indication signal may be simultaneously input into the third signal generation model, and the current output signal may be determined by the third signal generation model according to the auxiliary signal, the current indication signal and the model parameters.
Or the current output signal may be determined based on a consistency comparison between the auxiliary signal and the current indication signal. Optionally, consistency comparison can be performed on the auxiliary signal and the current indication signal to obtain a consistency comparison result; the current output signal may then be determined based on the consistency comparison result in combination with the current indication signal.
In this embodiment, the auxiliary signal is introduced, and the accuracy of determining the current output signal can be ensured by determining the current output signal according to the auxiliary signal and the current indication signal.
In order to ensure the running stability of the nuclear power plant, in this embodiment, an alternative method for determining the current output signal is provided, as shown in fig. 3, which specifically includes the following steps
S301, acquiring an auxiliary signal and a current indication signal.
Alternatively, after the auxiliary signal is determined with reference to step S201 described above, the auxiliary signal and the current indication signal may be acquired at the same time.
S302, judging whether the auxiliary signal is consistent with the current indication signal, if so, executing S303; if not, S304 is performed.
It can be understood that, since the gateway status signal is high (1) to indicate that the gateway running status is normal running and low (0) to indicate that the gateway running status is faulty, in practical application, the following four situations will exist, assuming that the gateway status signal is 1, the current indication signal is 1, and the auxiliary signal is 0; assuming that the gateway state signal is 1, the current indication signal is 0, and the auxiliary signal is 1; assuming that the gateway state signal is 0 and the current indication signal is 1, the auxiliary signal is 0; assuming that the gateway status signal is 0 and the current indication signal is 0, the auxiliary signal is 0.
Optionally, after the auxiliary signal and the current indication signal are obtained, whether the auxiliary signal and the current indication signal are consistent or not may be determined, and if so, the following step S303 is executed; if not, the following step S304 is performed.
S303, taking the history indication signal sent by the nuclear power instrument control system at the previous moment as a current output signal.
The history indication signal refers to an indication signal sent by the nuclear power instrument control system at the last moment.
Optionally, based on the deriving in step S302, if the auxiliary signal is consistent with the current indication signal, it is indicated that the gateway fails, and the current indication signal is at a low level, and at this time, because the indication signal has continuity, the history indication signal sent by the nuclear power instrument control system at the previous time can be directly used as the current output signal, and a gateway failure alarm is sent to the operation and maintenance personnel.
It can be understood that in practical application, the operation of the nuclear power equipment not only depends on the current output signal transmitted by the gateway, but also depends on the downstream equipment connected with the nuclear power equipment to send an indication signal to the nuclear power equipment, and at this time, the operation logic of the nuclear power equipment is that if the nuclear power equipment detects that any signal received is a low level signal, trip processing is directly performed. Therefore, under the condition that the auxiliary signal is consistent with the current indication signal, the downstream equipment can also transmit the low-level indication signal to the nuclear power equipment, so that the operation safety of the nuclear power equipment is ensured.
S304, taking the current indication signal as the current output signal.
Alternatively, as can be seen from the derivation in step S302, if the auxiliary signal and the current indication signal are inconsistent, it is indicated that the gateway is not faulty or the gateway is faulty, but the current indication signal is at a high level, and at this time, the current indication signal may be used as the current output signal.
In this embodiment, the problem that the low level is sent to the nuclear power equipment when the gateway fails but the current indication signal is at the high level can be avoided, so that the running stability of the nuclear power equipment is ensured.
In order to ensure the efficiency of the current output signal, in this embodiment, a reset/set RS flip-flop is integrated in the gateway, and further, another alternative method for determining the current output signal is provided, as shown in fig. 4A, which specifically includes the following steps:
s401, inputting an auxiliary signal to a reset end in a reset/set RS trigger integrated by the gateway, and inputting a current indication signal to a set end in the RS trigger, so that the RS trigger compares the auxiliary signal with the current indication signal in consistency, and determining a current output signal according to a consistency comparison result.
Alternatively, referring to fig. 4B, an auxiliary signal obtained by processing a gateway status signal and a current indication signal is input to a reset terminal (R terminal) in an RS flip-flop integrated with the gateway, and a current indication signal is input to a set terminal (S terminal) in the RS flip-flop, so that the RS flip-flop performs consistency comparison between the auxiliary signal and the current indication signal, and determines a current output signal according to a consistency comparison result.
S402, acquiring a current output signal output by the RS trigger.
Optionally, after the RS trigger determines the current output signal, the gateway may directly obtain the current output signal output by the RS trigger, and transmit the current output signal to the nuclear power device.
In the embodiment, the reset/set RS trigger integrated by the gateway is introduced, and the reset/set RS trigger is adopted to determine the current output signal, so that the determination of the current output signal can be facilitated, and the efficiency of signal determination is improved.
Fig. 5 is a schematic flow chart of a signal transmission method of a nuclear power plant in another embodiment, and on the basis of the foregoing embodiment, this embodiment provides an alternative example of the signal transmission method of the nuclear power plant. With reference to fig. 5, the specific implementation procedure is as follows:
s501, acquiring a current indication signal sent by a nuclear power instrument control system at the current moment.
S502, performing non-operation on the current indication signal to obtain an alternative signal.
Wherein, the gateway state signal and the current indication signal are both expressed by logic levels.
S503, performing logical AND operation on the gateway state signal and the alternative signal to obtain an auxiliary signal.
S504, inputting an auxiliary signal to a reset end in a reset/set RS trigger integrated by the gateway and inputting a current indication signal to a set end in the RS trigger, so that the RS trigger compares the auxiliary signal with the current indication signal in consistency and determines a current output signal according to a consistency comparison result.
Or the current output signal may be determined based on a consistency comparison between the auxiliary signal and the current indication signal. Specifically, if the consistency comparison result between the auxiliary signal and the current indication signal is consistent, taking the history indication signal sent by the nuclear power instrument control system at the previous moment as the current output signal; and if the consistency comparison result between the auxiliary signal and the current indication signal is inconsistent, taking the current indication signal as the current output signal.
S505, the current output signal output by the RS trigger is obtained.
S506, transmitting the current output signal to the nuclear power equipment so that the nuclear power equipment operates based on the current output signal.
The specific process of S501 to S506 may refer to the description of the foregoing method embodiment, and its implementation principle and technical effects are similar, and are not repeated herein.
